bpo-45621: Small changes to mmap (GH-29247)
* Small tidy-ups / comments
* Use randomized names when testing tagged mmaps to avoid any risk of parallel tests treading on each others' toes

bpo-40915: Fix mmap resize bugs on Windows (GH-29213)
(original patch by eryksun)

Correctly hand various failure modes when resizing an mmap on Windows:

* Resizing a pagefile-backed mmap now creates a new mmap and copies data
* Attempting to resize when another mapping is held on the same file raises an OSError
* Attempting to resize a nametagged mmap raises an OSError if another mapping is held with the same nametag

bpo-30555: Fix WindowsConsoleIO fails in the presence of fd redirection (GH-1927)
This works by not caching the handle and instead getting the handle from
the file descriptor each time, so that if the actual handle changes by
fd redirection closing/opening the console handle beneath our feet, we
will keep working correctly.

and set MAP_PRIVATE.

Zackery Spytz 14514d9084 bpo-36946: Fix possible signed integer overflow when handling slices. (GH-13375)
The final addition (cur += step) may overflow, so use size_t for "cur".
"cur" is always positive (even for negative steps), so it is safe to use
size_t here.

Nir Soffer 4484f9dca9 bpo-33021: Release the GIL during fstat() calls (GH-6019)
fstat may block for long time if the file descriptor is on a
non-responsive NFS server, hanging all threads. Most fstat() calls are
handled by _Py_fstat(), releasing the GIL internally, but but
_Py_fstat_noraise() does not release the GIL, and most calls release the
GIL explicitly around it.

This patch fixes last 2 calls to _Py_fstat_no_raise(), avoiding hangs
when calling:
- mmap.mmap()
- os.urandom()
- random.seed()
